Can I recover photos after my phone reset and they disappeared?

First, check that you’re signed in with the correct Apple Account. If the phone reset and you logged into a different account, an empty iCloud library would look exactly like this. Also check Photos > Albums > Recently Deleted, plus Recently Deleted on iCloud.com, since items may still be recoverable for up to 30 days. If the phone was ever connected to a Mac or PC, look for an older local backup too.

If the photos aren’t in the correct iCloud account, Recently Deleted, or a computer backup, recovery may not be possible. Photos and messages generally don’t vanish without the phone being erased, restored, or signed into a different account, so it’s worth figuring out what caused the reset before using the phone much more.
